Detroit ( dih-TROYT, locally also DEE-troyt) is the most populous city in the U.S. state of Michigan. It is situated on the bank of the Detroit River across from the Canadian city of Windsor, Ontario. It is the 26th-most populous city in the United States and the largest U.S. city on the Canada–United States border, with a population of 639,111 at the 2020 census, and an estimated 2025 population of 649,095. The Metro Detroit area, at over 4.4 million people, is the 14th-largest metropolitan area in the nation and second-largest in the Midwest (after the Chicago metropolitan area). The county seat of Wayne County, Detroit is a significant cultural center known for its contributions to music, art, architecture, and design, in addition to its historical automotive and industrial background.
In 1701, French explorers Antoine de la Mothe Cadillac and Alphonse de Tonty founded Fort Pontchartrain du Détroit. During the late 19th and early 20th centuries, it became an important industrial hub at the center of the Great Lakes region. The city's population rose to be the fourth-largest in the nation by 1920, with the expansion of the automotive industry in the early 20th century. One of its main features, the Detroit River, became the busiest commercial hub in the world. In the mid-20th century, Detroit entered a state of urban decay that has continued to the present, as a result of industrial restructuring, the loss of jobs in the auto industry, and rapid suburbanization. Since reaching a peak of 1.85 million at the 1950 census, Detroit's population has declined by more than 65 percent. In 2013, Detroit became the largest U.S. city to file for bankruptcy, but successfully exited in 2014. In 2025, the U.S. Census Bureau reported that Detroit's population grew for a second consecutive year and led population growth in Michigan for the first time since the 1950s.
Detroit is a port on the Detroit River, one of the four major straits that connect the Great Lakes system to the St. Lawrence Seaway. The city anchors the third-largest regional economy in the Midwest and the 16th-largest in the United States. It is also best known as the center of the U.S. automotive industry, and the "Big Three" auto manufacturers—General Motors, Ford, and Stellantis North America (Chrysler)—are all headquartered in Metro Detroit. Metro Detroit houses the Detroit Metropolitan Airport, one of the most important hub airports in the United States. Detroit and the adjacent Canadian city of Windsor constitute the second-busiest international crossing in North America, after San Diego–Tijuana.
Detroit's culture is marked with diversity, having both local and international influences. Detroit gave rise to the music genres of Motown and techno, and also played an important role in the development of jazz, hip-hop, rock, and punk. As a result of the city's rapid growth in its boom years, Detroit has many globally unique architectural monuments and historic places. Since the 2000s, conservation efforts have managed to save many architectural pieces and achieve several large-scale revitalizations, including the restoration of several historic theaters and entertainment venues, high-rise renovations, new sports stadiums, and a riverfront revitalization project. Detroit is an increasingly popular tourist destination which caters to about 16 million visitors per year. In 2015, Detroit was designated a "City of Design" by UNESCO, the first and only U.S. city to receive this designation.
Detroit is named after the Detroit River, connecting Lake St. Clair with Lake Erie. The name comes from the French language word détroit meaning 'strait' as the city was situated on a narrow north–south passage of water linking the two lakes. The river was known as le détroit du Lac Érié in the French language, which means 'the strait of Lake Erie'. In historical contexts, the strait included Lake St. Clair and the Detroit River.
Throughout its history, Detroit has been known by several nicknames. Its founder, Antoine de la Mothe Cadillac, originally envisioned the settlement as a major city within the Pays d'en Haut, calling it the Paris de la Nouvelle-France, (Paris of New France). As the city evolved into the world's automotive center, "Detroit" became a metonym for the industry itself. Its status as the heart of the automotive world is reflected in the nickname Motor City, while its deep musical legacy is famously celebrated through the moniker Motown.
Other nicknames emerged during the 20th century to reflect different aspects of the city's identity. It became known as the City of Champions in the 1930s following a series of sports successes, while the Detroit Red Wings later trademarked the name Hockeytown. In more recent years, it has been called the Renaissance City, a nod to its urban revitalization efforts and the iconic Renaissance Center complex. The city is also frequently referred to as The D, The 313 (its telephone area code), or Rock City, inspired by the Kiss song "Detroit Rock City."
Paleo-Indians inhabited areas near Detroit as early as 11,000 years ago including the culture referred to as the Mound Builders. By the 17th century, the region was inhabited by Huron, Odawa, Potawatomi, and Iroquois peoples. The area is known by the Anishinaabe people as Waawiiyaataanong, translating to 'where the water curves around'.
The first Europeans did not penetrate into the region and reach the straits of Detroit until French missionaries and traders worked their way around the Iroquois League, with whom they were at war in the 1630s. The Huron and Neutral people held the north side of Lake Erie until the 1650s, when the Iroquois pushed them and the Erie people away from the lake and its beaver-rich feeder streams in the Beaver Wars of 1649–1655. By the 1670s, the war-weakened Iroquois laid claim to as far south as the Ohio River valley in northern Kentucky as hunting grounds, and had absorbed many other Iroquoian peoples after defeating them in war. For the next hundred years, virtually no British or French action was contemplated without consultation with the Iroquois or consideration of their likely response.
On July 24, 1701, the French explorer Antoine de la Mothe Cadillac (1658–1730), with his lieutenant Alphonse de Tonty (1659–1727), and more than a hundred other Royal French settlers traveling south and west from New France (modern Province of Quebec), along the St. Lawrence River valley to the Great Lakes region, began constructing a small fort on the north bank of the Detroit River. Cadillac named the settlement Fort Pontchartrain du Détroit, after Louis Phélypeaux, comte de Pontchartrain (1643–1727), the Secretary of State of the Navy under King Louis XIV (1638–1715). Sainte-Anne de Détroit was founded on July 26 and is the second-oldest continuously operating Roman Catholic parish in the United States. France offered free land to colonists to attract families further west into the Great Lakes region interior of the North American continent to Detroit; when it eventually reached a population of about 800 by 1765, after the colonial conflict of the French and Indian War (1753–1763), (Seven Years' War in Europe), it became the largest European settlement between the important towns of Montreal and New Orleans, both also French settlements, in the former colonies of New France and La Louisiane (further south on the Mississippi River, on the coast of the Gulf of Mexico), respectively. The region's then colonial economy was based on the lucrative fur trade, in which numerous Native American peoples had important roles as trappers and traders.
During the French and Indian War (1753–63)—the North American front of the Seven Years' War in Europe between the Kingdom of Great Britain and the Kingdom of France—British troops gained control of the settlement a few years into the conflict in 1760 and shortened its name to Detroit. Several regional Native American tribes, such as the Potowatomi, Ojibwe and Huron, launched Pontiac's War (1763–1766), and laid siege in 1763 to Fort Detroit along the Detroit River in the Great Lakes but failed to capture it. In defeat, France ceded its territory in North America of New France and south of the lakes east of the Mississippi to the Appalachian Mountains to Britain following the war.
